Function
The KFD2-EB2.R4A.B?power supply module works with the
PS2500/PS3500 series backplanes. The power supply is well
suited for emergency shut down systems, fieldbus / HART
networks, as well as any general-purpose process
applications.
Each 24 V, 15 A module plugs directly into a 3- or 6-b
backplane allowing a maximum capacity of 45 A or 90 A of
uninterrupted power. The output voltage is adjustable from
22.5 V to 30 V DC via potentiometers on the backplane.
Universal b power is standard and allows a battery
backup, eliminating the need for a UPS connection. The
power supply modules are highly efficient (up to 91%) and use
natural convection cooling.
Each module operates with automatic load sharing, so
modules are hot swappable with no effect on the output
supply.
